UNITE SHUTTER-FASTENER.

SPECIFICATION forming part of Letters Patent No. 250,546, dated December 6, 1881.

Application filed March 24,1881.

To all whom it may concern Be it known that I, WILLIAM KAUFMAN, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Shutter-Fasteners; and I do hereby declare that the following is a full,clear,and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a partial side elevation of a win-- dow seat and shutter with my improved fastening applied; and Fig. 2 is a cross-sectional view of the same, showing the fastening.

This invention has relation to shutter-fast eners; and it consists in theimproved features of construction and combination hereinafter fully described, and particularly pointed out in the claim.

Referring by letters to the accompanying drawings, A designates a window-frame, and Bashutter. Anyordinaryshutter-workermay be employed to operate the shutter.

At the outer lower corner of the shutter B, and in the inner face of the stile, is a recess, 1", faced by a plate, 8, which forms a keeper for a finger, cl, upon the outer end of a rod, D, passing through the window-seat. The inner end of this rod D is provided with a knob or button, t, by which it may be operated to turn the finger [I either into or out of the recess 7'.

Through a slot in the inner end of the rod (No model.)

D is passed a pin, E, hooked or provided with an arm at its upper end, and having a finger, c, at its lower end.

On a line with the finger e, and in the face of the window-seat, is a recess, F, to receive the finger 6 when the pin E has been turned to lock the rod D tohold the finger cl in the recess r. The recess F is covered by a plate, G, having a slot, g, to prevent the finger efrom wearing the window-seat.

The shutter is locked by turning the finger 61 into the recess r, and then turning the pin E to cause the finger e to enter the recess F. The rod being locked from the inside, no effort from without, except the demolition of the shutter, can unlock it. v

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a shutter-fastener, the combination of the shutter B, having the IPCQSS r, the rod D, having finger d at its outer end to engage the recess 1', and the pin E, having finger e to engage a recess, F, in the inner face of the window-- seat, substantially as and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM KAUFMAN. Witnesses:
